Recuerdos del futuro

Von Däniken's approach is bold and controversial. I'm curious what sparked his interest in linking history and aliens, and how he decided which myths to include.

The book presents various artifacts and structures as potential proof of alien influence. I'm wondering how readers interpret the evidence—are these explanations plausible or more imaginative?

Von Däniken covers a wide range of cultures, but I wonder what guided his choices—was it the availability of artifacts, the stories themselves, or something else?
